Hi Simon,
I also stumbled sometimes ove this behaviour, but I think it is not a
real bug. If the parser has a list? predicate, it looks for

Hello everybody,
I just wrote a music function to mark grobs as editorial addition by
colouring them grey. See the code and an example:

(or (string? grob)
(list? grob)
